To all wlw/m, t may conc-ern.'

e it known that we, RoswELL S. TUCKER and HILAND l.. FanNswonTi-r, citizens of the United States, residing at Sandusky, in the county of Erie and State of Ohio, have invented new and useful Improvements in Brick-Scraping hlachines, of which the following is a specification.

rllhe invention relates to a. machine designed primarily for cleaning brick and similar structural elements, whereby such elements may be properly cleaned and reused for building purposes.

`'lhe main object of the present invention is the provision of a machine to which individual brick or similar element may be presented to arrange its successive sides and vends in contact with the cleaning element, and the refuse on the surface of the brick or the like readily stripped or cleaned therefrom. to permit a reuse of the brick for building or similar purposes.

The invention in the preferredform of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a view in side elevation of the improved machine. Fig. 2 is an end elevation of the same. Fig. 3 is a plan. Fig. 4 is a transverse section online tof F ig. 3. Fig. 5 is an enlarged perspective View of the cleaning roll.

The improved machine comprises a framework 1 including uprights 2 and cross pieces 3, the latter being arranged to form a rectangular framing adjacent the respective ends of the uprights. On the lower cross pieces 3 is mounted a mainshaft d on which within the plane of the uprights is mounted a belt wheel 5 driven by a belt 6 from any suitable source of power. Mounted on the upper cross bars is what 1 term the `operating shaft 7, which beyond the cross bars is provided with a belt wheel 8 connected by a belt 9 with the belt wheel l0 on the main shaft, whereby the operating shaft is properly rotated. The operating shaft is centrally formed'with a squared portion 11, provided at one end with an abutment 12 and threaded at the opposite end to receive a clamping nut 13. @n the operating r shaft intermediate the abutment and clamping nutare arranged a seriesoi2 cutters comprising disks 14 having peripheral 4cutting teeth 15 in the form of saw teeth. The disks are arranged upon the squared portion of the operating shaft in Contact, each disk being formed with a squared central opening of a size to snugly fit the squared p0rtion of the shaft, whereby the disks when in place are held fixed with relation to the shaft, so far as rotative action is concerned. The disks are arranged in contact one with another, with the teeth of adjacent disks relatively olfset, so that the teeth of each alternate disk are alined longitudinally of the roll formed by the disks. A. table 16 is pivotally mounted between the uprights at one end of the frame,`and at the opposite end rests upon an adjusting rod 17 threaded into a base plate 18 and operated by a hand wheel 19, whereby the free end of the table may be elevated as desired. The table is formed with an opening 20 through which the roll formed by the disks projects, the eX- tent of the projection being of course determined by the adjustment of the free end of the disk. A guard plate 21 is hingedly mounted upon the table, as at 22, said guard plate being connected through the medium of the rod 23 with the foot lever 24. The arrangement of the lever and rod is such that the operator by pressing upon the foot lever, will elevate the guard from over the roll, thereby exposing the latter for operation, and upon release of the foot pressure upon the lever, the guard will gravitate to closed position, to so protect the roll as to prevent liability of injury through accidental contact therewith.

In operation, the table is adjusted to eX- pose the roll in accordance with the thickness and character of the refuse material on the article to be cleaned. r1`he machine is then started to rapidly rotate the roll and the bricks or articles passed longitudinally of the table to permit the teeth of the roll to exert scraping and cutting action upon such refuse to clear the same from the surface of the article.

By the use of the improved apparatus, the bricks or similar articles may be readily and quickly cleaned of all refuse material, thus saving the very considerable amount of laborious hand effort usually required for this work.

`What is claimed isz- 1. A cleaning machine including a framework, a rotative y cleaning roll, a table through which a portion of the roll is eX- posed, a pivotally mounted guard for proexposed portion of the roll, and

tecting the for operating the guard to exa foot treadle pose the roll.

2. A brick cleaning machine including a framework comprising spaced uprights and cross pieces connecting said uprights, a cleaning roll mounted upon certain of said cross pieces, a table pivotally connected to certain of said uprights and having an opening through which a portion of the roll is exposed, a guard pivotally mounted to the top of the table for protecting the exposed portion of the roll, and a ioot treadle for operating the guard to expose the roll.

3. A brick cleaning machine including a 'framework comprising spaced uprights and cross pieces connecting said uprights, a cleaning roll mounted upon certain of said nosWnLL s. TUCKER. i-nLAND n. iuinnswon'rn.
